Problems solved by technology
[0003] In the worm gear and worm transmission device, the power is transmitted by the meshing between the worm gear and the worm gear. During the transmission process, the friction between the teeth is sliding friction, so the transmission efficiency is low, the processing technology of the worm gear is high, and the production is difficult. Use expensive anti-friction metal materials to manufacture worm gears, so it is necessary to seek solutions in the design and manufacture of worm gears; in the prior art, the connection between the worm gear and the transmission shaft in the worm gear transmission is generally bolts or screws. That is, the two can be connected axially and fixed circumferentially, but this connection method has limited shear resistance of bolts or screws, and it is easy to be sheared at the connection, causing failure

Embodiment Construction
[0024] A specific embodiment is enumerated below in conjunction with the accompanying drawings to further illustrate the present invention.
[0025] Such as figure 1 , figure 2 As shown, this embodiment is a connection sleeve, which includes an outer sleeve 1 and an inner sleeve 2 , and the inner sleeve 2 is set in the outer sleeve 1 .
[0026] Such as image 3 , Figure 4 As shown, the outer sleeve 1 is made up of two half cylinders, namely the first half cylinder 11 and the second half cylinder 12, the first half cylinder 11 and the second half cylinder 12 are coaxial, and the outer diameter of the two half cylinders equal, the inner diameters of the two half cylinders are not equal; the upper end surfaces of the first half cylinder 11 and the second half cylinder 12 share the same end surface, and the lower end surfaces of the two half cylinders share the same end surface.
[0027] Such as Figure 5 , Figure 6 As shown, the inner sleeve 2 is composed of two half cyl...

The invention provides a connecting sleeve comprising an outer sleeve and an inner sleeve, wherein the outer sleeve is composed of two semicircular cylinders, namely a first semicircular cylinder and a second semicircular cylinder, respectively, and the first semicircular cylinder is coaxial with the second semicircular cylinder; the inner sleeve is composed of two semicircular cylinders, namely a third semicircular cylinder and a fourth semicircular cylinder, respectively, and the third semicircular cylinder is coaxial with the fourth semicircular cylinder; the outer sleeve sleeves the inner sleeve. The connecting sleeve is capable of connecting a worm gear with a worm gear transmission shaft safely and reliably, and enabling the worm gear and the worm gear transmission shaft to restrain mutually and rotate axially together; the connecting sleeve also has the advantages of simple structure and low cost.
